Characteristic of brick of tall aluminium of light qualitative heat preservation reachs useless brick utility

Tall aluminous brick calls light qualitative heat preservation tall aluminous adiabatic brick again. Among them alumina content is in the 48% above, light qualitative fireproof material that basically constitutes jointly by Molaishi and corundum. Bulk density is about between 0.4 ～ 1.35g/cm3. Apparent pore rate is in about 66% ～ 73% between, compression intensity 1 ～ 8MPa. Have good heatproof shake performance.


Light qualitative tall aluminous brick uses tall aluminous aluminous grog to add a few clay normally, produce law or bubble law with gas via be being used normally after mill with slop form pouring, figuration, via 1300 ～ fire of 1500 ℃ high temperature and into. Also can replace grog of alumina of partial tall aluminium with industrial alumina sometimes.
Tall aluminous brick can use light qualitative heat preservation at build by laying bricks or stones to build thermal insulation and erode without stock of melt of intense high temperature reach erode the place of action. When be being contacted with blaze directly, the temperature of watch surface contact of general tall aluminous qualitative adiabatic firebrick does not get prep above 1350 ℃ . Mo Laishi pledges adiabatic firebrick can contact blaze directly. Have high temperature resistant, intensity is high, energy-saving effect is distinct wait for a characteristic. Apply to roller of the furnace that heat up solution, hot-blast stove, pottery and porcelain kiln of drawer of porcelain of path kiln, report and the liner of all sorts of resistor furnace. The corundum that Al2O3 content is 82.4 ％ - firebrick of Mo Laishi heat insolation, can use in lining of 1550 ℃ dirty.
Brick of tall aluminium of deserted light qualitative heat preservation regards utility of useless brick of brick of tall aluminium of light qualitative heat preservation as clinker in joining saggar preform, its action has the following. ① acquires the poriferous organization that saggar place asks, send density with what will adjust base substrate, improve the micromechanism of base substrate. ② reduces figuration moisture content, accelerate the dry rate of base substrate. ③ decreases dry reach firing and contractive. ④ increases porosity, improve permeability, increase thermal stability. ⑤ increases firing hind saggar intensity.
